SPECIFICATION forming part of Letters Patent No. 470,407, dated March 8, 1892. Application filed December 15 1890. Serial No. 374,762. (No model.)

To all whom, it may concern:

Be it known that I, WILLIAM H. CRAW- FORD, a citizen of the United States, residing at \Veatherford, in the county of Parker and State of Texas, haveinvented a new and useful Stirring-Machine, of which the following is a specification.

This invention relates to agitating-machines adapted to be used for various purposes; and the object of the same is to produce a machine of this character capable of such uses.

To this end the invention consists of the specific details of construction hereinafter more fully described and claimed, and as illustrated in the two sheets of drawings, wherein Figure 1 is a perspective view of this device When used as a Washing-machine, the cover of the clothes-box being slightly raised. Fig. 2 is afront elevation of this machine with the open frame therein, showing the cylinder in section supported by the frame and the dasher within the cylinder. Fig. 3 is a similar front elevation showing a tub in section as resting on the base and showing in elevation the cylinder within the tub and the cross-frame for causing its rotation. Fig. 4 is a side elevation of the driving mechanism complete. Fig. 5 is a cross-section through the upper gear and the shaft. Fig. 6 is an enlarged perspective detail of the dasher with its wing folded inwardly. Fig. 7 is a central longitudinal section of the clothes-box.

Referring to the said drawings, the letter B designates the base, from which rise three uprights U, connected at their upper ends by a cross-frame X. Above this frame is an extension E,through one side of which is journaled the main shaft m, carrying the main gear-wheelN and having a crank-handle e at its outer end. Journaled in the orossframe X is a tubular shaft '1, having a shouldered lower end 25, and secured upon the shaft above the frame is a gear-Wheel V, which meshes with the main gear N. At the upper end of the extension E is another gear G, held normally in place and. in engagement with the main gear bya bracket E of the extension, and passing vertically through the upper end of the extension E, through the upper gear G,

and through the tubular shaft T is a shaft S,

having alongitudinal slot S in its body,which engages a pin G across the opening through the hub of the upper gear, and this shaft is provided with a squared lower end .9 and hole 3' through its body slightly above said end and an enlarged upper end or knob 8 By this construction when the crank e is turned the main gear Ndrives the gears G and? in opposite directions, and hence causes the solid shaft S and tubular shaft T to turn oppositely.

The letter C designates the clothes-box of a Washing-machine, which has laterally-projecting pins 0, adapted to engage holes or hooks to in the uprights U, as seen in Fig. 1. Within this box is arranged a removable corrugated bottom 0', mounted upon longitudinal cleats C C is the cover to this clothes-box, which is made in twoparts connected by hinges hand having a hole H through its center. After this box has been arranged in position, with the pins 0 engaging the hooks to, the dasher, or more properly the agitator A, is brought into position within the clothes-box, so that its depending feet a shall pass over the corrugated bottom 0. This agitator is an X- shaped frame, from which rises a tubular shank A that passes through the hole H in the cover and loosely embraces the lower end of the shaft S. This shank is provided with a transverse hole a, adapted to register with that lettered s in the shaft, and when a pin a is put through these holes the agitator is connected to the shaft S and will be rotated thereby when the crank e is operated.

" The letter F designates an open frame, which carries an open or solid rotary base F, having a central depending stud f, which turns in a step b at the center of the base B. The upper end of the frame F is provided with a tubular shank A the same as that of the agitator, except that it has a shouldered upper end 75 the same as the lower end of the tubular shaft. When this frame is put in The letter Y designates a cylindrical dish having a closed lower end provided with a central depending stud f and inside with a central step Z), and this dish or cylinder is supported, when its stud does not rest in a step, by three or more depending feetf The cylinder Y has a cover Y provided with acentral aperture or hearing y and with ears 3 as shown.

The letter D designates a dasher, which comprises a main vertical shaft having a conical lower end forming a stud adapted to fit and turn in the step 19 within the cylinder Y. Extending horizonally from this shaft 3 paddle is thrown out orin, according to the direction in which the dasher is rotated. The lower end of the dasher-shaftis seated in the upper end extends through the collar 1 and has a square hole D adapted to receive the squared lower end 8 of the shaft S.

latter mounted in astep b in the lower end of the tub, the 'dasher above described inserted in the cylinder, passed through the: bearing .3 of the cover Y, and connected with the squared lower end of the shaft S, and a cross-frame 0 brought into place to connect the tubular shaft with the body of the cylinder.

of which it is rotated and whereby the cylinder is turned in one direction; but the solid shaft, extending through the tubular shaftin-to the interior of 'th e cylinder and con nected This cross-frame comprises a horizon-1 'tal arm-adapted to engage the ears y on the cover, and from the center of this horizontal f arm rides a tubular shank A having ashouldered upper end if, the same as the upper 1 end of the frame F. The tubular shank sur- 1 rounds the solid shaft S and engages the f lower end of the tubular shaft T, by means so as to prevent it sticking to the can or dasher, and the cylinder is movedwithin the ice so as to prevent an uneven freezing of the cream. If desired, the cross-frame can be omitted and only the dasher rotated within the cylinder.

When the device is used as a washing-machine, the clothes are placed in the clothesbox 0 and the dasher, or more properly the agitator A, connected to the lower end of the shaft S and rotated or oscillated, as above described.

It will thus be seen that this improved device is useful for a variety of purposes; but in all cases the frame-work, the driving mechanism, the hollow and solid shafts, (the latter moving vertically,) a receptacle, and a dasher are employed. WVith a washing-machine the hollow shaft is uselcss. \Vith a churn the open frame F and cylinder Y are used, and with a freezer the cross-frame 0, cylinder Y, and tub Z are used. The vertical movability of the solid shaft is useful to disconnect it fromthe dasher, and in the last two cases to allow the frame andcylinder-to be withdrawn, and the shank of either frame and lower end of the tubular shaft are formed with L-shaped shoulders, which readily disengage transversely when the vertical shaft is with- If the frame F is mounted in the step in l the base and its shouldered upper end con-i nected with the lower end of the tubular, shaft, the driving mechanism will cause the frame to turn in a direction opposite to that 1 in whichthe dasher turns, and hence af This is 1 very useful for churning, and toward the; last of the process the direction of rotation may be reversed, whereby the paddle d will 5 be dragged behind its pivots, rather than;

When the tub Z is placed upon the base, as shown in Fig. 3, the device becomes an icecream freezer-that- :is to say, the ice and salt are placed in thetub around the cylinder, the

bevel-gear between said top and bracket, a solid shaft having a squared lowerend,:alongitudinal slot in its body and a knob at its upper end,the shaft extending loosely through the tubular shaft, the hubs of both gears, and the cross-frame, bracket, and top of the extension, a pin across the hub of the upper bevel-gear passing t'hroughsaid slot,a cranked operating-shaf t j ournaled in the extensiomand a main gear thereon in constant mesh with both said bevel-gears, of a receptacle removably mounted on the base and having a hole through its cover, and a dasher journaled in said hole and havingasoc'ket in its shaft detachably connected with said squared lower end, all as and for the purpose set forth.
